E-bike drive-system diagnosis
Lifty investigates selected hub and mid-drive e-bike systems for noise, loss of assistance, sensor errors, cable damage and intermittent drive. The motor is assessed with the battery, controller, display and sensors because these systems work together.
Symptoms we investigate
- No pedal assistance or intermittent assistance
- Grinding, clicking or bearing noise
- Motor cable or connector damage
- Speed, cadence or torque-sensor faults
- Error messages and power loss under load
Some proprietary motor systems require manufacturer diagnostic software or authorised parts. Lifty confirms support before accepting the job.
Can every mid-drive motor be opened?
No. Serviceability and parts access vary widely. Replacement or referral may be more appropriate for sealed or manufacturer-controlled units.
Could brake drag feel like a motor problem?
Yes. Brakes, tyres, drivetrain and wheel bearings are checked where relevant because mechanical resistance can reduce performance and range.
